Are you saying, go with an O/D with 3.78, go with an O/D with 3.54 or just go with the 3.54?

Thanks
The gain from rpm reduction at freeway speed.OD/3.78 or OD/3.54..at 62mph OD 3.54 the rpm is 130 less and at the bottom of the torque range..makes it a little more pleasant to drive.700 bucks (Terry's cost for a 3.54 upgrade) more pleasant? that's debatable.
